Question

An engineer must design a curved exit ramp for a highway in such
away that a car, exiting at the posted speed limit of
17.88m/s (40 mi/hr), does not depend on friction
toround the curve without skidding. The radius of the curve is
166.0m.
a) At what angle with respect to the horizontal must thecurve be
banked (in degrees)?
b) Find the speed of a satellite in a circular orbit aroundthe
earth with a radius 3.53 times the mean radius of the
earth;RE 6.37E+3km; ME
